.SHORT TERM (Tonight through Thursday Night)...
Upper air analysis this morning showed zonal flow across the southern
US. At the surface, high pressure was centered over the Gulf and
winds across our CWA were from the south to southwest. An upper level
trough will dig down along the west coast during this period turning
the upper flow over Texas to the southwest. The low level flow will
remain southerly. An upper level short wave trough will move through
the pattern and may provide enough lift to produce isolated showers
and thunderstorms over the west tonight and spread to the east
Thursday.

&&

.LONG TERM (Friday through Wednesday)...
The upper pattern will remain fairly stationary through the end of
the week with the trough digging mainly south while rotating slowly
through the southwest. Sunday an upper trough will move in from the
Gulf bringing a chance for showers and thunderstorms to the eastern
part of our CWA. The upper pattern will become more progressive
Monday with the trough moving across the Rockies and into the Central
Plains. The tail end of this trough will hang back over the southwest
and eventually close off into a low over Arizona by Tuesday night.
This will mean an extended period with chances for rain Monday
through Wednesday.
